Cabling Instructions
CAUTION:
THE FOLLOWING GUIDELINES ARE GENERAL RECOMMENDATIONS.
ALL APPARATUS MUST BE INSTALLED IN ACCORDANCE WITH THE
MANUFACTURER’S INSTRUCTIONS AND WITH THE RELEVANT
HAZARDOUS AREA INSTALLATIONS STANDARDS/CODES OF PRACTICES.
ALL ELECTRICAL CABLING MUST BE INSTALLED BY TECHNICALLY
TRAINED PERSONNEL USING TRADE, PROFESSIONAL OR
LOCAL/INTERNATIONALLY RECOGNISED STANDARD PROCEDURES.
Route the display and power cables into the controller enclosure through the gland specified on the
system installation GA Drawing. If the appropriate cable gland is not specified on the system
installation GA Drawing then use the cable gland nearest the internal connection point. Segregation
between safe area circuits and intrinsically safe circuits is mandatory.
Within the enclosure, ensure that a 50mm separation exists between “safe area circuit” terminals and
“intrinsically safe circuit” terminals.
Do not coil excess display cable outside or within the RCI-4100 enclosure – always cut off excess
cable.
Blue-jacketed cable commonly denotes an “intrinsically-safe circuit” when located in a hazardous
zone.
Check that the blue-jacketed cable, supplied by LSI-Robway, is used for all “intrinsically safe circuits”
only. Always trap the shield of all cables in the Ex d glands of the controller.
“Intrinsically safe circuit” cable shield must only be connected to ground at the controller end and
terminated within the gland. Do not allow cable screens to continue inside the controller enclosure.
In the enclosure, do not ground the shield of screened cables to grounding points other than glands.
Blue-jacketed cable
must not
be used for “safe area circuits” such as power supply, slew encoder or
angle sensor because these are not “intrinsically safe circuits”.
Check that “safe area circuit” armoured cable is used for the power supply, slew encoder and angle
sensor. This cable armour must be connected to earth at both ends. If manufacturer's instructions
are followed, the Ex d cable gland is suitable for this purpose, by trapping the steel armour.
Do not run signal cables next to power cables anywhere on the crane. There should be separate
cable trays for the two types of cables. This is to avoid electrical interference.
All safe area cabling and intrinsically safe circuit cabling must be protected from physical damage
and UV degradation.
Do not ground screened cable shields at both ends – they only need to be trapped in the gland at the
enclosure.
It is recommended that “Denso” tape or a similar approved tape/sealant be applied around all
connectors subject to external weather to minimise moisture ingress.
